STEEL STAMP.

Application filed April 2, 1925. Serial No. 20,160.

To all whom it may concern Be it known that I, ORLAND F. BAUGH- MAN, a citizen of the United States, residing at Lakewood, in the county of Cuyahoga and State of Ohio, have invented a certain new and useful Improvement in Steel Stamps, of which the following'is a full, clear, and exact description, reference being had to the accompanying drawings.

This invention relates to steel stamps that are used especially for marking metal articles, and it has to do more particularly with an improved holder for a group of individual steel type which go to make up the stamp. I

The purpose of my invention is to provide a device of the aforesaid character into which a number of separate type in any desired orderinay be quickly and easily inserted and from which they likewise may be removed, thus facilitating the original setting of the type and permitting conven ient substitution of onetype for another, or a rearrangement of the type, all of which tend toward a saving of time in the use of the implement, especially when it is used for serially numbering a succession of articles.

'Further objects of the invention are to provide a very substantial and durable hold or for steel type, and one which is simple of construction, comparatively inexpensive of manufacture, and which may be readily repaired in case any of the type retaining springs become broken.

The foregoing objects, with othershereinafter appearing, are attained in the embodiments of the invention illustrated in the accompanying drawing wherein Fig. 1 is'a perspective view of one form of the invention; Fig. 2 is a central longitudinal section through the device shown in Fig. 1;

Fig. 3 is a transverse section on the line 33 of Fig. 2; Fig. 4: is a fragmentary longitudinal section through a modified form of the invention; and Fig. 5 is a sectional detail on the line 55 of Fig. 4;.

The holder consists of an elongated body 1 of suitable metal, such as steel. It is shown as rectangular in cross section, and at one end is provided with a socket 2 that is of a size and shape to receive with a. relatively close fit a given number of steel type 3.

Secured, as by screws 5, to one side of the body 1 is a bar 6 within which are anchored the ends of spring-wire fingers 7, the free ends of saidfingers being turned back upon themselves, as indicated at 8 in Fig. 2, and projected through holes 9 that are formed in theadjacent wall of the socket 2.v In the absence of the type 3, the fingers 7 project into the socket 2, as indicated in dotted lines in Fig. 2, but when thetype are inserted into the socket, the spring fingersare camined outwardly to the position shown in full-lines. The fingers 7 are relatively stiff and exert sufficient pressure upon the type to securely hold them by friction against accidental dislodgment. There is an individual spring finger for each type so that any one of the type may be removed and another one substituted for itwithout disturbing the other type of the group. In some instances a blank slug or-so-called spacer is used in place of a type as when a number is to be stamped having a less number of digits than the number of type vyhich the socket 2 'isdesigned to acconnno- (ate. 7 r. r l

In Figs. 4 and 5 I have illustrated amoditication of the invention wherein leaf springs 7 are used in place of the spring.- wire fingers 7. springs are shown as secured to the bar 6 as by being wrapped around the bar, that portion of each spring which extends be ueath the bar occupyinga channel that is formed on the inner side of the bar, as clearly shown in Fig. 5. This-arrangement facilitates the replacement of any spring which becomes weak or broken.

In using the stamp as a hand tool the workman grasps itibetween the thumb .and fingers of one hand and places it in the de sired position on the object to be marked, and with a hammer held in the other hand delivers a blow to the upper end of the holder. By slightly modifying the shank of the holder in a well known manner, the device may be adapted for use in presses.

Having thus described my invention, what I claim is:

1. A device of the character set forth comprising a body portion having a type receiving socket, and a plurality of spring fingers severally secured to one side of said body portion, the adjacent side wall of the socket being cut away and the ends of said spring fingers being projected therethrough for holding engagement with type within the socket, each finger engaging an individual The ends of said leaf.

type and functioning independently of the pitlaer fingers, as and for the purpose speoi- 2. A device of the character set forth comprising an elongated body portion having a type receiving socket opening through one of its ends, the socket being of a size and shape to receive a given number of type, one of the side walls of the socket having openings corresponding in number and location to the type accommodatingspaces of the socket, a member rigidly secured to the body portion, and a series of spring fingers having one of their ends'anchored to said memberand their otherends projected through the aforesaid openings for engagement with type in the socket, each finger engaging an individual type and functioning independently of the other fingers, as and for the purpose specified.

3. A device of the character set forth comprising an elongated body portion hav ing a type receiving socket opening through one of its ends, the socket being of a size and shape to receive a given number of type, one of the side walls of the socket having openings corresponding in number and location to the type accommodating spaces of the socket, a member applied to the body portion, and a series of spring fingers having one of their ends anchored to said member andtheir other ends projected through the aforesaid openings for frictional engagement with type in the socket,-the latter ends of said fingers being bent over upon themselvesthereby to present rounded ends to the type, each finger engaging an individual type and functioning independently of the other fingers, as and forthe purpose specifi d v v i 4:. A device of the character set forth comprising an elongated body portion having a type receiving socket opening through one of its ends, said socket being of a size and shape to receive with a relativelyclose fit a given number of type, one of the side walls of the socket having a plurality of openings shape to receive with a relatively close fit a given number of type, one of the side walls of the socket having a plurality of openings corresponding in number and location to the type accommodating spaces of the socket, a bar disposed transversely of one side of the body portion and removably secured thereto, said bar being spaced from the aforesaid openings, and leaf springs having one of their ends Wrapped about said bar while their other ends are projected through said openings for engagement with type in the socket, the underside of said bar being channeled to accommodate said leaf springs.

6. A device of the character set forth comprising an elongated body portion having a type receiving socket opening through one of its ends, said socket being of a sizeand shapeto receive with a relatively close fit a given number of type, one of the side Walls of the socket being cut away to expose the sidesof type within the socket, a bar disposed transversely of one side of the .body portionand removably secured theretoysaid bar having grooves on its inner face, and

spring fingershaving one of'their ends confined Within said grooves while their other ends are projected into holding engagement with type in the socket.

In testimony whereof, I hereunto aflix my signature,

ORLAND F. BAUGHMAN.
